Uneven road surface

The road surface on great south road /butterworth ave intersection is uneven. The road has been plagued with lots of heavy and sometimes overweight trucks and as they hit the uneven parts of the road it sends shock waves through the ground and has been damaging nearby homes. This issue has been highlighted in the past and was fixed temporarily but the problem is now worse. The weight of trucks passing and the way the road is acting leads me to believe that the roads roots have not been created strong enough. The trucks also speed and this also does not help.
